How would you account for the increasing oxidising power in the Example series `VO_(2)^(+) lt Cr_(2)O_(7)^(2–)lt MnO_(4) ^(-)`

A

`VO_(2)^(+) lt Cr_(2)O_(7)^(2-) lt MnO_(4)`

B

`Cr_(2)O_(7)^(2) lt VO_(2)^(+) lt MnO_(4)^(-)`

C

`Cr_(2)O_(7)^(2-) lt MnO_(4)^(-) lt VO_(2)^(-)`

D

`MnO_(4)^(-) lt Cr_(2)O_(7)^(2-) lt VO_(2)^(+)`

Text Solution

Verified by Experts

The correct Answer is:
A

Oxidising power increases with increase of oxidation number of central atom.
`Mn (O.S.)` in `MnO_(4)^(-) = +7`
`Cr (o .S.)` in `Cr_(2)O_(7)^(2-) = +6`
`V (O.S.)` in `VO_(2)^(+) = +5`
